EJECTION MEANS FOR REVOLVERS Charles Edward Rowe, Athol, Mass., assignorto Harrington &Richardson Arms Company, Worcester, Mass, a corporationof Massachusetts Application December 27, 1949, Serial N 0. 135,075

acla ms. (01. 42-68) This invention relates to manual. ejection meansfor the fired shells of revolvers particularly of the solid frame type,in which the cylinder must be removed in order to eject the spentcartridge shells.

The principal object of the invention resides in the provision ofejection means for a solid frame revolver or the like, comprising acenter pin on which the cylinder rotates as the revolver is fired topresentanew cartridge to the hammer and barrel, said pin being easilyremovable allowing the cylinder to be dropped out of the solid frame,and said cylinder having ejection means therein to be manually actuatedby said pin but only when both pin and cylinder are completely removedfrom the revolver.

Another object of the invention resides in the provision of ejectionmeans as above stated, said ejection means being removable from thecylinder in one rotative position only thereof, said ejection meanscomprising an indented plate adapted to underlie the rims of rim firecartridges and including a hollow cylinder thereon having acircumferential groove adjacent an end thereof opposite the plate, saidcylinder being flat on one side from the plate to the groove, and saidgroove forming a shoulder which is fiat at a side opposite the flattenedarea of the ejector cylinder, in combination with means in the revolvercartridgecylinder forming a central chamber receiving the ejectioncylinder, said chamber having a flattened boss at one end allowingentrance of said flange in one rotative position only of the ejectionmeans, said boss allowing the ejection means to rotate when aligned withthe said groove and the flattened part of the ejection cylinder allowingthe latter to slide down into the cartridge cylinder into operativeposition therein.

Other objects and advantages of the invention will appear hereinafter.

Reference is to be had to the accompanying drawings in which Fig. 1 is aview in side elevation of a revolver according to the present invention,parts being broken away;

Fig. 2 is an enlarged view of the cylinder pin and latching meanstherefor;

Fig. 3 is a cross section through the cylinder illustrating the actionof the ejecting means;

Fig. 4 is a rear elevational view of the cylinder showing the samepartly loaded;

Fig. 5 is a front view in elevation of the ejecting device; and

Fig. 6 is a front view in elevation of the revolver with the gripremoved.

The present invention relates mainly, but not exclusively, to solidframe revolvers and, this application is therefore illustrated withrelation to a revolver having a solid frame l0 inwhich there is provideda cylinder opening foreartridge cylinder I2, which cylinder is removableonly laterally, but to either side of frameiO. The frame I0 is, ofcourse, provided with barrel l4, trigger l6, hammer l8 and grip 20, asis con.- ventiona-l. 3 f

Solid frame It) is provided with a pair of semicircular laterallyextending cylinder abutment plates 22 and 24 to the rear of thecylinder, plate 24 having slot 26 for loading thefcylinder l2 cartridgeby cartridge, as the cylinder-is rotated; but, alternatively, thecylinder mayjbe removed, loaded, and replaced as is apparent.

The cylinder I2 is provided with a separable pin 28 on which it rotatesas advanced by the trigger or hammer action as "is well known in theart, pin 28 serving as a center shaft. The frame Ill is provided with asmall notch as for instance, at 30 to receive the tip 32 of the pin 28;and axially across the cylinder opening, it is provided with a passage34, notch-30 andpassage 34 providing holding means axially 16-- catedrelative to cylinder l2 mounting the latter rotatively. Pin 28 is heldin position by means of a pivoted latch 36 taking into a notch 68 andhaving a spring 40 located in the frame ill. Latch 36 has an outwardlyextending portion 42 to be engaged by the finger of the operator wherebyto depress the same against the action of spring 40 and rotate latch 36suificiently to disengage it from pin 28 whereupon the latter may bewithdrawn and the cylinder l2 dropped on Cylinder I2 is provided with aseries of small bores 44 receiving cartridges 46 and at its rear face itis provided with a depression 48 extending part way into the bores, andshaped to receive an ejector plate 50 which is provided with a series ofsmall peripheral semi-circular cartridge-receiving recesses, the ejectorplate fitting into the depression 48 and completing the same to formstops for the rims of the cartridges 46. As is plainly seen, it ismerely necessary to move ejector plate 50 outwardly of the cylinder l2,see Fig. 3, to remove the empty cartridge cases 52', all of thesecartridge cases being removed simultaneously.

The ejector plate 50 is integrally joined to a central sleeve or tubularmember 52, the bore of which is formed with an annular shoulder 54 at 5one end to receive shoulder 56 of the pin 28.

Hence, all that it is necessary to do to extract.

3 the cartridges is to actuate the latch 36 as above described, removethe pin 28, drop out cylinder I2, insert pin 28 within the hollowcylinder 52 and move the latter outwardly, as shown in Fig. 3, thusejecting all of the empty shells.

Pin 28 is then removed from the cylinder 52, the latter is replaced sothat plate 50 is located in the depression 48 and the cylinder is thenreloaded and re-inserted in the solid frame I0, thereupon being held inposition by pin 28.

The tubular member 52 is cut away or flattened along one side as at 58from plate 50 to a circumferential recess or circular groove 60. Thisgroove forms a shoulder or flange 62 which is flattened diametricallyoppositely as at 64 from the flat 58. The central chamber 52 of cylinder[2 is provided with a lug or the like 66 at the forward end there of andthis lug or projection prevents complete removal of the ejector devicewhen it is pushed to the left in Fig. 3, by the pin 28 because of theabutment of shoulder 62 therewith. In addition, the flat 58 rides onthis boss and the same prevents the ejector cylinder 52 from rotating sothat the ejector plate 50 always must fit into the notch 58 in exactlythe same way.

In order to extract the ejector, it is merely necessary to withdraw thesame until boss 66 aligns with groove 60 and in this position, theejector is allowed to rotate. A 180 turn will then bring fiat portion 64in alignment with boss 66 whereupon the entire ejector is removed andmay be replaced in similar manner.

It will be seen that thi invention provides an inexpensive firearm ofthe solid frame type having a convenient and easy shell ejection devicein which the cylinder center pin is manually utilized to extract all ofthe empty shells at once.

Having thus described my invention and the advantages thereof, I do notwish to be limited to the details herein disclosed otherwise than as setforth in the claims, but What I claim is:

1. In a solid frame revolver formed with a cylinder openingcommunicating with the barrel, a shell cylinder in said opening, saidcylinder having an axial bore and an abutment at the inner end of saidbore, ejector means including an ejector plate engageable with the rimof shells carried by said cylinder and a tubular member connected withsaid plate and slidable axially within the bore of said cylinder fromshell-loading position to shell-ejecting position, the inner surface ofsaid tubular member having a shoulder portion, the outer surface of saidtubular member having a longitudinally cut away portion to accommodatesaid abutment so as to permit said axial movement but oppose rotationalmovement of said tubular member relative to said cylinder, the outer endof said tubular member having a projecting part engageable with saidabutment when said tubular member is slid to shell-ejecting position,thereby to prevent removal of said ejector means from said cylinder, anda cylinder pin projecting through said frame and extending axiallythrough said tubular member so as to support said cylinder for rotation,said pin being removable to permit detachment of said cylinder from saidframe and when detached said pin being engageable with said shoulderportion to operate said ejector means.

2. A revolver as set forth in claim 1, wherein said tubular member iscircumierentially recessed between its outer end and said projectingpart so that said tubular member may be rotated when in shell-ejectingposition, thereby to permit said ejector means to be separated from saidcylinder.

3. A revolver as set forth in claim 1, wherein said tubular member iscylindrical and the longitudinally cut away portion is in the shape of achordal flat, and said abutment is in the form of a segmentcomplementing said chordal flat, and said tubular member is formed witha circumferential groove between its outer end and said projecting partso as to permit rotation of said tubular member when in shell-ejectingposition to disengage said abutment and projecting part and permit saidejector means to be separated from said cylinder.
